Abstract

The thermo-reversible formation of wormlike micelles from a polystyrene- block -polyethylene- block -poly(methyl methacrylate) (PS- b -PE- b -PMMA) triblock terpolymer with a crystallizable middle block in organic media is presented. The formation of wormlike micelles is rather unexpected, because PE containing diblock copolymers usually form platelet-like structures. Transmission electron microscopy (TEM) investigations revealed a core−corona structure for the wormlike micelles. The core is formed by crystalline PE domains, and the soluble corona exhibits a patched structure composed of microphase-separated PS and PMMA chains. Microphase separation of the coronal chains was proven by 2D 1 H nuclear Overhauser effect spectroscopy (NOESY) and TEM investigations of selectively stained samples. A combination of various techniques, such as differential scanning calorimetry (DSC), dynamic light scattering (DLS), and scanning force microscopy (SFM), indicated that the wormlike micelles might be formed by crystallization-induced aggregation of spherical micelles upon cooling. The presented approach opens an alternative way to produce anisotropic polymer nanostructures with a microphase-separated corona.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
